Anderson Jacobson

Anderson Jacobson, also known for a time as CXR Anderson Jacobson and today as CXR Networks, is a vendor of communications equipment. Anderson Jacobson was an early manufacturer of acoustic modems and was spun off from SRI International (then the Stanford Research Institute).[1] In the 1970s and 1980s, the company manufactured modems, some intended for consumers.[2] The company was acquired by CXR Telecom in 1988,[1][3] at which time The Times was following Anderson Jacobson's earnings reports.[4] The flow of new products continued.[5]

Anderson Jacobson was primarily a California-based[8] manufacturer of acoustic coupler modems, but they also manufactured printing terminals designed to replace teletypes.


Modems

Anderson Jacobson began early in 1967 as a manufacturer of one of the first acoustic data couplers. This technical advancement was a step beyond directly wiring to phone lines.[9] By 1973, the company had acoustic coupler products that transmitted at 150, 300 and 1200 baud.[10]

Terminals

Some of their terminals were CRTs and others were Printer/Keyboard devices.

Among the terminals that were marketed by Anderson Jacobson are:[11]

Model Type Announced Price Image(s) Notes
AJ 510 CRT May 1979 $1,995
AJ 841 KB/Printer February 1973 $2,995 printer uses IBM Selectric electric typewriter mechanism[12]

CXR

After the merger, industrial references varied, including "Anderson Jacobson (CXR)" [13]

CXR was purchased by Emrise Corporation an international manufacturer of defense and aerospace electronic devices and subsystems and telecommunications equipment.[14] and, in 2016 sold for 690,000 British pounds to its former chairman/CEO.[15]

CXR, described as "manufactures network telecommunications equipment," was still operating as of 2017, albeit not in the areas for which AJ had begun in 1967.[7]

gollark: Some calculators will support `log` with two parameters, one of which is the base, so just `log(number, base)`.
